CVE-2017-7652

HIGH

Eclipse Mosquitto 1.0-1.4.14 - Denial of Service via Configuration Reload

Title source: llm

Description

In Eclipse Mosquitto 1.4.14, if a Mosquitto instance is set running with a configuration file, then sending a HUP signal to server triggers the configuration to be reloaded from disk. If there are lots of clients connected so that there are no more file descriptors/sockets available (default limit typically 1024 file descriptors on Linux), then opening the configuration file will fail.
